Abstract
The utility model provides a flame-retardant anti-explosion device of a water-cooling type lithium ion battery, which comprises the lithium ion battery and a safety valve. The flame-retardant anti-explosion device is characterized in that the lithium ion battery is arranged in a box body, the box body is composed of a lower shell and an upper cover, and water is filled in the lower shell to soak the lithium ion battery. The structure of the anti-explosion device is reasonable, the water-cooling method is adopted on the lithium ion battery, and the lithium ion battery together with the safety valve forms the anti-explosion double insurance; meanwhile, the anti-explosion device is safe as well as reliable, has the flame-retardant effect, and is suitable for being used on large-sized batterypacks such as an automobile battery and the like.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment, particularly a kind of water-cooled lithium ion battery fire and explosion resistant device.
Background technology
Existing lithium ion battery explosion-proof device generally has two kinds: a kind of is that the expanding gas that produces when utilizing battery overcharge is washed safety valve open, stops charging thereby cut off the electricity supply; Also having a kind of is to produce high temperature when utilizing battery overcharge, thereby makes the temperature sensing device action, stops charging thereby cut off the electricity supply.But these apparatus structures are all perfect inadequately, in case safety valve or temperature sensing device are malfunctioning, then can cause danger, and are safe and reliable inadequately.And all there is not fire-retardant effect.
The utility model content
It is a kind of rational in infrastructure, safe and reliable that the purpose of this utility model is to provide, both can be explosion-proof, and water-cooled lithium ion battery fire and explosion resistant device that again can be fire-retardant.
The purpose of this utility model can reach by following measure: a kind of water-cooled lithium ion battery fire and explosion resistant device, comprise lithium ion battery, safety valve, it is characterized in that: lithium ion battery is loaded in the box body of being made up of lower casing, loam cake, water is housed in lower casing, is soaking lithium ion battery.
The purpose of this utility model can also reach by following measure: on cover and be provided with safety valve, unidirectionally go into water valve, sealing wire sleeve pipe and location fin, loam cake and lower casing are tightly connected, the power supply lead wire of lithium ion battery is drawn from the sealing wire sleeve pipe, and water is gone into water valve and injected in the lower casing from unidirectional.Be provided with located lateral fin and longitudinal register fin in the lower casing, with on the location fin that covers to cooperate be the lithium ion battery location.Lithium ion battery can be the battery pack of multi-disc.
The utility model has following advantage compared to existing technology: rational in infrastructure, the mode to lithium ion battery employing water-cooled constitutes explosion-proof dual fail-safe with safety valve; Has fire-retardant effect simultaneously; Safe and reliable, be applicable on the large-sized battery pack such as automobile batteries.
Description of drawings
